At 40 °C it carries a steady 63 A without derating, and the curve holds flat to 50 °C — only drops to 58 A at 70 °C, so you can pack it into a warm enclosure without losing much headroom. Breaking capacity is what you'd expect from a compact MCCB in this frame: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. Auxiliary switch pack has two HQ-form contacts; shunt trip (STL) release included.
Dimensions: 130 mm tall, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint. If you're commissioning a panel in an unheated warehouse in January, it'll close and carry load at -25 °C without issues.
